The Fijiana finished fifth at the opening leg in Dubai in December and head coach Iliesa Tanivula said their goal remains to become a semifinal regular.
"We just didn't take our chances in the quarter final against England - we thought we gave it away," he said.
"We put a lot of pressure on ourselves and made a couple of silly mistakes but it's something that we've spoken about as a squad.
"We've really worked hard and the girls have really really bought into it so just looking forward to this weekend."
This is the first year Sydney has hosted a Women's World Series event.
However a number of women's knockout matches on the Saturday have been moved across the road from the sold out Allianz Stadium onto a training field that seats less than 1000 people, in order to allow the men's pool matches to be played inside the main stadium.
Iliesa Tanivula said it was a shame but they still expected to receive lots of support.
"I guess it is what it is and we've just got to get on with it and there's games to be played and these girls have worked hard and (we just have to) get on with it," he said.
"I know these girls - most of them have got their families and their friends in Australia.
"It's something we are looking forward to, playing in Sydney, and hopefully our fans and our friends will get behind the team and cheer them on."
The Fijiana will face Ireland, Brazil and Olympic champions Australia in pool play.
Meanwhile, Papua New Guinea will be competing in their first Women's World Series event and are in the same pool as New Zealand, Canada and France.
